ABSTRACT:
A multi air conditioning system for adjusting the amount of refrigerant flowing into indoor units determined to be in a stopped state, to improve the overall system efficiency, and a method for operating the multi air conditioning system. The method includes determining whether or not some indoor units are in a stopped state; measuring temperatures of heat exchangers of the indoor units in the stopped state; and changing opening degrees of valves installed in those indoor units determined to be in the stopped state to change the amount of refrigerant flowing therein if the temperatures of the heat exchangers of the stopped indoor units deviate from a reference range.
